The sport is moving away from the traditional practice of the same gender playing against each other, with competitors set to face a comparable opponent.

"It's great for both the beginners and more developed players to know that they'll be playing people of a similar ability," Tennis NSW tournament coordinator Michael Spry said.

"It's a game-changer because it's usually been boys or girls, men or women separated."

Under the previous system, a junior player, for example, could tackle same-aged opponents with far greater skill and experience.

"We can have instances where a player will enter their first tournament and have a negative experience and we may lose that player, we're moving away from grouping on purely age," Tennis NSW head of tennis operations Matt Rippon said.
